Find out the detailed answer to the 20 12 Tianjin senior high school entrance examination question 25, question 3.
When c' falls on OA, connect CC', △ cc' a △ OPB, ∴ AC' = T, c' o = c' p = PC =11-T.
If PM is perpendicular to the X axis in M, then PM = 6, Mo = t, ∴ C'm = 1 1-2t.
△C'MP, according to Pythagorean theorem, we can establish a quadratic equation about t, and just solve t!
